Measure the item you want to hold, set how snug the cradle should be, and get a printable Skadis hook with standard pegs on the back. Deterministic and free.
Hang a tool, cable or gadget off an IKEA Skadis pegboard. Standard Skadis pegs on the back, a cradle sized to your item on the front.
Diameter or width of the thing the hook cradles, e.g. a tool handle or a cable.
How far the hook reaches out from the board. The Fit slider does not change this.
How loose the printed part sits on the thing it mates with. Looser prints fit more easily.
Snug adds 0.10mm, Normal adds 0.25mm, Loose adds 0.50mm to the surface that mates with your object, so the printed part clears it without extra sanding.
